It might help if you start FS with "-monotonic-clock". This usually makes the timing more accurate. However, on a VM you can never be sure.

Also, if I understand your first post correctly, when this error is shown, it will bring down FS completely? If that's the case that must be reported to Jira, since this is a bug (a crash is always a bug).

To make sure that timing is ok, always run on real hardware.

If you’re going to run FreeSWITCH inside a virtualized Windows Instance, you may as well go with Microsoft’s Hyper-V. Windows Server seems to work better under Hyper-V than Xen or OpenVZ.

You could try assigning the VM a higher CPU weight, (not sure how VMware handles that) to see if that solves the issue.

Try another type of virtual machine. Xen seems to work well, openvz is recommended by the devs. Other than that make sure your resources are allocated properly.
